You thought you'd have to wait until 2008 for some Gran Turismo fun, didn't you? Well you can stop thinking that right now as the latest piece of news to come out of the PlayStation Premiere event in Tokyo is an announcement that GT 5 prologue will be available in Japan in October. What is effectively a demo for Gran Turismo 5 will feature full online support as well as some cars which will be featuring in this year's Tokyo Motor Show.
Whether it will be available in the US or EU in October is up in the air, however it's fairly safe to assume it will be out before the end of the year. There is no word yet on what the price will be for the download, considering the current PSN offering is downloadable for free.
